2 Claims.

This invention relates to a watchmakers tool.

The primary object of this invention is to provide a device of the above character which is particularly adapted for removing the sweep second wheel from its supporting shaft without disturbing or disassembling the remainder of the watch mechanism.

A further important object of this invention is to provide a device of the above character by which the sweep second wheel of watches may be removed Without bending or otherwise distorting the supporting shaft or sweep second wheel.

Still another important object of this invention is to provide a device of the above character by which the sweep second Wheel of a Watch mechanism may be readily removed from its supporting shaft by applying a slight radial pressure to the under side thereof.

A still further object of this invention is to provide a device of the above-mentioned characarrangement of parts may be resorted to, without ter which is of simple construction, and one which may be readily manufactured and placed upon the market at a reasonable cost.

The foregoing and other objects and advantages will be apparent throughout the course of the following description and drawing, in which,

Figure 1 is a top plan view of the device associated with the sweep second wheel of a watch mechanism.

Figure 2 is a side elevation of the device as depicted in Figure 1; and I Figure 3 is a front end elevation of the tool.

Referring in detail to the drawing, the device consists of an elongated shank or body I of substantially rectangular configuration in crosssection, or of any other suitable design,

The body I has a handle 2 secured to one end thereof by means of a transverse pin or rivet 3.

The opposite end of the body I is provided with a downwardly extending leg 4 disposed at substantially right angles to the body and having its lower free end bifurcated as at 5 so as to provide a pair of vertically aligned and spaced leg members 6, 6.

The lower free ends of the legs 6, 6, each has a forwardly extending part 1, the upper surfaces of which are inclined rearw-ardly and upwardly so as to form in eiiect a wedge-shaped toe portion.

In operation,-and by Way of example, if it is desirable to remove the sweep second wheel 8 from its supporting shaft 9, the tool is disposed over a spoke I0 of the wheel so that the same is received in the bifurcation 5. The tool is then moved towardor in a radial direction with respect to the spoke and hub of the wheel so that the wedge or toe portions I slide between the hub and base plate to apply pressure in a direction so as to remove the wheel from its supporting shaft.

It has been found that in the use of this tool departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, what Iv claim as new and desire to secure by Letters Patent is:

1. A tool of the character described for removing a spoked sweepsecond wheel from an assembled watch mechanism without disassembling the latter including an elongated rigid one-piece handled body having a free end extending at right angles thereto, said free end being bifurcated so as to provide a pair of alined spaced legs, and wedge means secured to and extending forwardly of each of said legs adjacent the free ends of the latter, whereby the bifurcated end of the tool may be disposed over one of the spokes of a sweep second wheel and the wedge means inserted beneath the hub of said wheel for removing the latter,

2. A tool of the character described for removing a spoked sweep second wheel from an assembled watch mechanism without disassembling the latter including an elongated rigid onepiece body member of substantially rectangular configuration in cross-section, a handle secured to one end of the body, an arm carried by and extending at right angles to the body at the opposite end of the latter and having its outer free end bifurcated to provide a pair of spaced alined legs, and a wedge-shaped member carried by the free end of each of said legs and extending forwardly at right angles thereto and in substantial parallel alinement with the longitudinal axis of said body, whereby the bifurcated end of the tool may be disposed over a spoke of a sweep second wheel and the wedge-shaped members ining the latter.
